我可以用CURLOPT_HTTPHEADER多次调用curl_setopt来设置多个头吗？ [英] Can I call curl_setopt with CURLOPT_HTTPHEADER multiple times to set multiple headers?

问题描述

我可以使用 CURLOPT_HTTPHEADER 调用 curl_setopt code>多次设置多个标头？

  $ url ='http://www.example.com/ '; 
 
 $ curlHandle = curl_init（$ url）; 
 curl_setopt（$ curlHandle，CURLOPT_HTTPHEADER，array（'Content-type：application / xml'））; 
 curl_setopt（$ curlHandle，CURLOPT_HTTPHEADER，array（'Authorization：gfhjui'））; 
 
 $ execResult = curl_exec（$ curlHandle）; 
  




解决方案

方法在中的这个回答Php - 调试卷曲 ）回答了问题：不，不能使用 CURLOPT_HTTPHEADER 调用 curl_setopt 。第二个调用将覆盖第一个调用的头。

相反，函数需要调用一次所有头文件：

  $ headers = array（
'Content-type：application / xml'，
'授权：gfhjui'，
）; 
 curl_setopt（$ curlHandle，CURLOPT_HTTPHEADER，$ headers）;相关（但不同的）问题是：

 如何获取先前使用curl_setopt（）设置的选项？（curl PHP扩展）
 
  
Can I call curl_setopt with CURLOPT_HTTPHEADER multiple times to set multiple headers?
$url = 'http://www.example.com/';

$curlHandle = curl_init($url);
curl_setopt($curlHandle, CURLOPT_HTTPHEADER, array('Content-type: application/xml'));
curl_setopt($curlHandle, CURLOPT_HTTPHEADER, array('Authorization: gfhjui'));

$execResult = curl_exec($curlHandle);

解决方案
Following what curl does internally for the request (via the method outlined in this answer to "Php - Debugging Curl") answers the question: No, it is not possible to use the curl_setopt call with CURLOPT_HTTPHEADER. The second call will overwrite the headers of the first call.

Instead the function needs to be called once with all headers:
$headers = array(
    'Content-type: application/xml',
    'Authorization: gfhjui',
);
curl_setopt($curlHandle, CURLOPT_HTTPHEADER, $headers);
